AI Article Synopsis
- The arterial switch operation can lead to late complications like coronary artery stenosis or occlusion, as illustrated by a case of a young boy with an occluded left anterior descending artery (LAD) diagnosed before age 3.
- He underwent bypass surgery but faced issues like anastomotic stricture and kinking of the graft, highlighting the challenges in pediatric cardiac procedures.
- At age 7, he had reversible ischemia, leading to successful retrograde percutaneous coronary intervention (PCI) performed by a team of pediatric and adult cardiologists, which is significant for treating such cases in younger patients.
Article Abstract
The arterial switch operation for correction of transposition of the great arteries can be complicated by late stenosis or occlusion of the coronary arteries that are re-implanted to the new aorta. We report the case of a young boy who underwent this operation as a neonate and was found to have an occluded anomalous left anterior descending artery (LAD) before age 3. Subsequent bypass surgery was complicated by anastomotic stricture and kinking of the left internal mammary artery graft to the LAD. At age 7, the LAD territory showed reversible ischemia on nuclear perfusion testing and he was referred for percutaneous coronary intervention. A combined approach with pediatric and adult interventional cardiologists resulted in successful retrograde PCI to recanalize the chronic total occlusion of the LAD. Important features of this technique in pediatric patients are discussed.
